Key Operational Challenges Faced by Fabricators

Top Features of MES to Enhance Operational Efficiency

MES features ensure achieving efficiency over every aspect of the production process, from inventory management to quality control, fostering efficiency, reducing waste, and ensuring compliance. In this context, we present a detailed exploration of the key MES features, their underlying technologies, and the tangible benefits they bring to the fabrication shop floor.

Workflow and Order Scheduling

Manufacturing Execution Systems (MES) offer fabricators advanced scheduling options, such as priority-based scheduling, forward scheduling, and backward scheduling. These techniques allow the recalibration of the production process in accordance with current capabilities and constraints to optimize workflow and order scheduling.

How does it work?

• Priority-based Scheduling: Fabricators can rank jobs based on importance, deadlines, or profit to prioritize urgent projects.
• Forward Scheduling: This method calculates the earliest possible finish time, starting as soon as possible to meet fixed start dates. It’s ideal for sectors requiring immediate production, such as doors and storage.
• Backward Scheduling: Used for tasks with strict deadlines, it determines the latest possible start time to ensure critical end dates are met, essential for constructions like awnings or cladding.

These scheduling options leverage advanced algorithms that account for various factors, including machine availability, labor skills, and material lead times, ensuring optimal order scheduling.

What is the impact?

Implementing these scheduling techniques via MES substantially enhances production efficiency, allowing fabricators to adjust quickly to new orders and minimize idle times. This adaptability is crucial for industries where production is often linked to client events or construction schedules. By prioritizing and efficiently managing resources, fabricators can accelerate production throughput, reduce operational costs by minimizing overtime and expediting fees, and increase customer satisfaction through timely deliveries.

Real-Time Production Monitoring

Real-time production monitoring enables fabricators to detect anomalies, machine failures, or production bottlenecks. This capability is particularly crucial for industries such as cabinet manufacturing, where precision and timing are key to maintaining high standards of production. MES systems provide a powerful layer of intelligence by integrating Internet of Things (IoT) technology, which facilitates the immediate identification and rectification of production issues.

How does it work?

• Detection and Alerts: MES uses IoT sensors installed on machinery and equipment to continuously monitor and collect data on various parameters, such as operational performance, machine conditions, and production quality. When these sensors detect any deviation from the norm, such as a discrepancy in the dimensions of sheet metal cuts, they trigger alerts and notifications, enabling them to take swift corrective actions.
• Start / stop timers: These timers are started or halted based on data received from IoT (Internet of Things) sensors and user inputs. The help to accurately track the operational status of machinery and production processes.
• Issue escalation: Issue escalation promptly addresses and resolves issues that impact production efficiency. It begins with the detection of anomalies through IoT sensors, followed by an initial assessment to determine the problem’s severity. The issue is escalated based on predefined protocols to ensure it is addressed by experts, such as floor operators, engineering specialists, or management.
• Data Aggregation and Visualization: The data collected by IoT sensors is aggregated and analyzed by the MES. This information is then presented on custom interactive dashboards, providing real-time oversight and actionable insights into the production process.

What is the impact?

• Enhanced Operational Efficiency: Immediate detection and rectification of production anomalies allow fabricators to maintain continuous production flow and high equipment effectiveness. This not only prevents machine failures, but also optimizes the production process by reducing waste.
• Quality Control and Cost Reduction: For processes such as the fabrication of metal doors, real-time monitoring ensures that bending and cutting processes operate within specified tolerances, avoiding rework or scrap. This level of control directly contributes to higher-quality outputs and lowers production costs by minimizing waste and unnecessary downtime.

Inventory and Material Management

Inventory and material management involves the strategic oversight and optimization of inventory levels, leveraging RFID (Radio-Frequency Identification) and barcode technologies. This feature is crucial for maintaining an efficient production line, especially for those specializing in custom projects like cladding, where material requirements can vary significantly from one job to the next. The aim is to implement just-in-time (JIT) inventory practices, a lean manufacturing principle focused on reducing excess stock and minimizing waste.

How does it work?

• Tracking and Monitoring: RFID and barcode technologies are employed to meticulously track and monitor materials from receipt through to their use in production. This precise tracking capability enables fabricators to maintain real-time visibility over their inventory, tracking each sheet of metal, hardware component, or accessory.
• Insight and Optimization: MES analyzes the data collected through RFID and barcode scans. Fabricators gain detailed insights into material usage patterns. This information is crucial for optimizing stock levels and ensuring that the right materials are available in the right quantities at the right time, without overstocking or understocking.
• Automated Reordering: Integration with supply chain management systems allows for the automation of the reorder process. Based on actual inventory levels and production needs, materials are replenished dynamically, reducing the need for manual intervention and ensuring materials are available when needed.

What is the impact?

• Streamlined Production Process: By minimizing excess inventory, fabricators can streamline their production process, free up warehouse space, and reduce operational costs associated with storing unnecessary materials.
• Cost Reduction: Avoiding the purchase of surplus materials not only frees up capital, but also minimizes the costs associated with handling and storing unused inventory.
• Optimized Material Usage: For sheet metal fabricators, who often deal with a variety of materials, such as aluminum, steel, or copper, having a system that can dynamically adjust to production needs based on actual usage is invaluable. This ensures that each material type is used efficiently, reducing waste and controlling costs.

Maintenance Management

Maintenance management in manufacturing execution systems (MES) leverages predictive analytics and machine learning to forecast equipment failures before they occur.
